"'He's coming to himself,' said Peggotty.
"Mr. Peggotty touched me, and whispered with much awe and reverence, 'They are both a-going out fast.'
"He now opened his eyes.
"I was on the point of asking him if he knew me, when he tried to stretch out his arm, and said to me distinctly, with a pleasant smile,--
"'Barkis is willin'.'
"And, it being low water, he went out with the tide." [342]
That the rise and fall of our tides twice a day, with spring and neap tides twice in the lunar month, are the effect of the combined action of the sun and moon, is never called in question. The water under the moon is drawn up from the earth, and the earth is drawn from the water on the opposite side, the consequence of which is two high tides in the two hemispheres at the same hour. The rotation of the earth bringing the same point of the ocean twice under the moon's meridian, once under the upper meridian and once under the lower, each hemisphere has two high tides in the course of the day. The spring tide is caused by the attractive force of the sun and moon acting in conjunction, or in a straight line; and the neap tide is caused by the moon being in quadrature, or when the sun and moon are at right angles to each other. They counteract each other's influence, and our tides arc therefore low. So much is science; but the connection of ebb and flow with life and death is superstition.
From a very remote antiquity, in the twilight of natural astrology, a belief arose that changes in the weather were occasioned by the moon. [343] That the notion lives on, and will not soon die, is clear to any one who is conversant with current literature and common folk-lore. Even intelligent, well-informed people lend it countenance. Professor Newcomb, of Washington, rightly says: "Thus far there is no evidence that the moon directly affects the earth or its inhabitants in any other way than by her attraction, which is so minute as to be entirely insensible except in the ways we have described. A striking illustration of the fallibility of the human judgment when not disciplined by scientific training is afforded by the opinions which have at various times obtained currency respecting a supposed influence of the moon on the weather. Neither in the reason of the case nor in observations do we find any real support for such a theory. It must, however, be admitted that opinions of this character are not confined to the uneducated." [344] Mr. Edward B. Tylor holds similar language: "The notion that the weather changes with the moon's quarterings is still held with great vigour in England. That educated people to whom exact weather records are accessible should still find satisfaction in the fanciful lunar rule, is an interesting case of intellectual survival." [345] No marvel that the "heathen Chinee" considers lunar observations as forecasting scarcity of provisions he is but of the same blood with his British brother, who takes his tea and sends him opium. "The Hakkas (and also many Puntis) believe that if in the night of the fifteenth day of the eighth month (mid autumn) there are clouds obscuring the moon before midnight, it is a sign that oil and salt will become very dear. If, however, there are clouds obscuring the moon after midnight, the price of rice will, it is supposed, undergo a similar change." [346]
One of our provincial proverbs is: "So many days old the moon is on Michaelmas Day, so many floods after." Sometimes a proverb is a short saying spoken after long experience; at other times it is a small crystal left after a lengthy evaporation. In certain instances our rural apothegms are sacred relics of extinct but canonized fictions. An equally wise prediction is that if Christmas comes during a waxing moon we shall have a very good year; and the nearer to the new moon, the better. But if during a waning moon, a hard year; and the nearer the end of the moon, so much the worse. Another sage belief is that the condition of the weather is dependent upon the day of the week upon which the new moon chances to fall. We are told that "Dr. Forster, of Bruges, well known as a meteorologist, declares that by the Journal kept by his grandfather, father, and self, ever since 1767, to the present time, whenever the new moon has fallen on a Saturday, the following twenty days have been wet and windy, in nineteen cases out of twenty." [347] In Italy it is said, "If the moon change on a Sunday, there will be a flood before the month is out." New moon on Monday, or moon-day, is, of course, everywhere held a sign of good weather and luck.
That a misty moon is a misfortune to the atmosphere is widely supposed. In Scotland it is an agricultural maxim among the canny farmers that--
